Hanna (HI775) Chkr hc colorimeter; alk-fresh water
Hanna HI775 Checker HC Colorimeter for Alkalinity Testing in Freshwater
Handheld digital colorimeter for accurate alkalinity measurement in freshwater systems, aquariums, and aquaculture applications
Precision alkalinity measurement for freshwater environments
Colorimetric Analysis
Uses advanced optical technology to measure alkalinity with accuracy that matches benchtop equipment, eliminating guesswork from visual color matching
Freshwater Optimized
Calibrated specifically for freshwater alkalinity ranges common in aquariums, ponds, and aquaculture systems where buffering capacity is critical
Portable Design
Compact handheld form factor allows testing at the source, whether monitoring RO waste streams, aquarium stability, or process water quality
Fast Results
Digital readout provides results in minutes with clear numerical values in mg/L or ppm, making it simple to track alkalinity trends over time
Application range
The Hanna HI775 Checker HC is designed for freshwater alkalinity testing in aquariums, ponds, aquaculture facilities, and water treatment systems. Works with Hanna HI775-26 reagent packs (sold separately). Not suitable for saltwater or marine alkalinity measurement. Ideal for monitoring buffering capacity in RO/DI systems, post-remineralization testing, and livestock water quality verification.
Reagent replacement schedule
HI775-26 Reagent
Each test requires one reagent packet. Available in boxes of 25 tests. Store reagents in cool, dry location away from direct sunlight
Cuvette Cleaning
Rinse cuvette with deionized or distilled water between tests. Replace cuvette if scratched or cloudy to maintain measurement accuracy
Battery Replacement
Replace AAA batteries when low battery indicator appears. Keep spare batteries on hand for uninterrupted testing in critical applications
Lab Accuracy
Digital precision eliminates subjective color interpretation
Battery Powered
No calibration solutions or complex setup required
Numerical Readout
Easy to log and track alkalinity trends over time
Professional Grade
Trusted by aquaculture professionals and water labs
